We have 8,625 miles on our 2025 Suburban. We were going down the highway when began to hear a unfamiliar noise. We pulled over into an error to inspect and didn't notice anything under the vehicle, which we thought might have cause the noise. We put into drive and went less than an 1/8 of a mile and our suburban lost acceleration and stopped. It would not start and couldn't not be moved, until roadside assistance took it to a Chevrolet dealership. The dealer stated the engine seized up and needs to be replaced. We were fortunate we were not going any more than 20 miles per hour and were not on a major highway.
The engine failed right in the middle of a intersection completely shut down, locked up the motor

Was driving on highway and engine started to make a noise, performance and power were impacted, the engine service light appeared. Exited highway on near offramp, when on offramp vehicle engine stopped working. Vehicle is a 2025 Chevrolet Suburban with 6.2L engine. Dealer has stated engine is seized. Seems exactly like the current 6.2L engine recall for 2021-2024 model years that results in engine failure. Vehicle is 7-8 months old, and only has roughly 12,000 miles.
While driving we received a notification on our dash board stating “reduced acceleration drive with caution”. We had it towed to the dealership where they said we needed a full engine replacement. It took 22 days to get the vehicle back

Engine failed going 70mph on highway at 2k miles. Display said acceleration no longer available and app said transmission code was needing to be checked however once taking to dealer I was told it was an oil sensor then told there was shredded metal in my engine and I needed a full engine replacement. My car was in the dealership for over 50 days. I was pregnant and with two small children in the car when engine failed at high speeds. After my car was returned to me the engine overheated and failed again. The dealer claimed GM sent them an engine with cut hoses. I was 9 months pregnant when this occurred also on the highway going 65mph. GM refused to buy back the vehicle 3 times.
